Momentum and CollisionHard
Question
Consider an ideal gas confined in an isolated closed chamber. As the gas undergoes an adiabatic expansion, the average time of collision between molecules increases as Vq, where V is the volume of the gas. The value
of q is :-
of q is :-
Options
A.
B.
C.
D.
Solution
t ∝ 
t ∝ V1 T-1/2
For adiabatic process
t ∝ V1-γ
t ∝ V1T-1/2 ∝ Vγ+1/2
comparing
t ∝ V1 T-1/2
For adiabatic process
t ∝ V1-γ
t ∝ V1T-1/2 ∝ Vγ+1/2
